LOOIVI FOR WEAVING DOUBLE PILE FABRICS.

SPECIFICATION forming part of Letters Patent No. 307,747, dated November 11, 1884:.

Application filed November 7, 1882.

To all whom it may concern:

Be it known that I, CHARLES COUPLAND, of Seymour, in the county of New Haven and State of Connecticut. have invented certain Improvements in Looms for W'eaving Double- Pile Fabrics, of which the following is a specification.

This invention relates to looms for weaving double-pile fabrics, such consisting of dupli' cate fabrics united by intersecting threads, which, when subsequently divided, form two single fabrics, each'having a pile or velvet surface.

Heretofore there have been devised looms for weaving in which double shuttle-boxes have been used in connection with a skeleton race placed above the lower or usual race; but in such cases no suitable provision has been made for the convenient removal of the shuttle, when required, without interference with the skeleton race or with the warp.

The object of my said invention is to pro vide a ready and convenient means for removing and replacing the upper shuttle in its box when occasion requires, and thereby to prevent any interference on the part of the said shuttle, when being thus removed, with the warps or with the skeleton race.

My said invention consists in a novel combination of lower shuttle-boxes and lay-beam, upper shuttle-boxes, top rail, and a skeleton race, with hinged or removable sides applied to the upper shuttle boxes, the whole constructed and arranged to effectually secure the object aforesaid.

In the drawings, Figure 1 is a front view of the upper portion of the lay of a loom having the invention applied thereto. Fig. 2 is a view, on a larger scale, of one end of the lay. Fig. 3 is a transverse sectional view taken in line m 00 of Figs. 1, 2, and 4. Fig. 4c is a plan view of the end shown in Fig. 2. Fig. 5 is a perspective detailed view,- and Fig. 6 is a plan View corresponding to Fig. 4, but with the lateral gate, forming one side of the upper shuttle-box, swung open to permit the removal or replacement, as the case may be, of the shuttle in its box.

At each end of the lay is a pair of shuttleboxes, A and 13, each being designed for the reception of a separate shuttle, and the one,

(No model.)

B, being placed over the other, A. The shuttle from the lower boxes, A, is designed to traverse the race formed by the upper surface of the lay-beam a, which is arranged in the same relation to the lower boxes, A, as in the ordinary single-shuttle-box looms.

O is the top rail of the lay, and D is the reed.

Extending down from the top rail, (3, are a series of prongs or fingers, E, the lower ends of which are bent inward or backward, as represented in Fig. 5, thereby forming a skeleton race, in substantially the same horizontal plane as the bottoms of the boxes B. The prongs or fingers E are placed at such distance apart that their lower parts, 0, will support the upper shuttle in its passage through the warps. The object of this skeleton race is to provide a means for supporting the upper shuttle in its movement while forming the upper web of the fabric, without permitting the upper shuttle itself to run in contact with the upper warp. The lower parts, a, of the skeleton race, constituted by the prongs or fingers E, are so arranged that the lower warp may rise between them in the operation of weaving, and are tapered in such manner that the warps may readily pass between them without catching, and a space should be afforded between their rear extremities and the reed, in order to allow the filling to draw down for the purpose of being beat up, as will be readily understood by those familiar with the practical construction and operation of looms.

In order that the two shuttles A and B may be simultaneously projected over the respective races, as indicated in Fig. 1, the horizontal partition f, which constitutes the bottom of the upper shuttle-box, and also the top of the lower shuttle-box, on each end of the lay, is longitudinally slotted, as represented in Fig. 3, and at g in Fig. 4. A peculiarly-constructed double picker, F, is arranged to move through both of the said boxes, the said picker being represented in side elevation in Fig. 3, the upper part, in, of said picker traversing the upper shuttle-box, while the lower part, n, of said picker traverses the lower shuttle-box, the said upper and lower parts, m and a, of said picker F being connected by a neck, 1', as represented in said Fig. 3.

' opening extending the entire width of the interior of the shuttle-boxes, and being of a length, measured in a direction longitudinally of the shuttle-boxes, slightly exceeding the thickness of the picker F, so that the latter may be readily dropped into place and into position for longitudinal movement within the shuttle-boxes. A single picker-staff of the ordinary or any usual construction is arranged in substantially the same relation with the picker F as the common picker-staff is arranged with regard to a single picker of an ordinary singleshuttle-box loom, so that the single picker-staff, acting through the double picker F, gives simultaneous motion to the two shuttles from the two sh uttle-box'es B and A, the two shuttles being thrown together andin unison alternately from the one pair of shuttle-boxes to the other. I

In order to provide for the removal of the upper shuttle from either of the upper boxes, when desired, without interfering with the warps and the skeleton race Reach of the upper boxes, B, instead of being made with both its sides or lateral portions rigid or permanently fixed, has one of its said sides movable, so that the same can be brought away from its normal position to an extent sufficient to enable the contained shuttle to be taken out or replaced.

As represented in Figs. 4 and 6, the outer side of the shuttle-box is formed as a gate, I,

pivoted at its outer end, as shown at i, and held in a closed position by a catch of suit able construction, (indicated as a bolt or pin at 70 in Figs. 2, 4, and 6.) When this gate is closed, as represented in Figs. 2 and 4, it constitutes the outer side of the box, and assists in guiding the shuttle as the latter glides into or from the same.

In order to remove or replace the shuttle, the side or gate I is turned outward, as rep resented in Fig. 6, thereby enabling the shuttle to be taken laterally from its place, and to be in like manner put back again, without involving the necessity of moving the shuttle lengthwise from the box, and thereby bringing it more or less in conflict with the warps and with the skeleton race F, the operation of removing and replacing the shuttle being by this means very greatly facilitated, and injury to the warps or web being avoided.

While this construction of the shuttle-box is more particularly designed for the upper shuttles, it may be .used, when desired, in connection with the lower shuttles, although ordinarily the latter may be removed endwise in the ordinary manner without material inconvenience.

In order to guide, support, and steady the picker during its movement, there is provided a fixed horizontal rod, (i which passes through a slot or opening of corresponding size and shape formed in the upper part of the picker, as more fully shown in Fig. 3.

Except for the purposes of the combination hereinafter set forth in the claim, I do not herein claim the herein-described skeleton race, inasmuch as the said skeleton race constitutes an element in combinations claimed in certain other applications for Letters Patent filed by meas, for example, in my application filed November 7, A. D. 1882, and designated by the serial number 76.153. Further, I .do not herein claim the double picker, inasmuch as said picker is set forth in the specification and claims of my separate and distinct application for Letters Patent filed November 7, A. D. 1882, and indicated by the serial number 76,153.

What I claim as my invention is- The combination of the following elements, to wit: lower shuttle-boxes, A, and lay-beam a, upper shuttle-boxes, B, rail 0, skeleton race E, and hinged or removable sides applied to the upper shuttleboxes, substantially as described, whereby the shut-tle may be removed therefrom or replaced therein without interference with the said skeleton race or with the warps, all substantially as herein set forth. CHARLES OOUPLAND.
